In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.

Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.

Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

Answer: True, all chemicals should be treated as if you don’t know what they are.

Explanation:

All chemicals should be treated as if you do not know what they are. In this way you can protect yourself and others from potential hazards, as chemicals can be mixed up or confused.

The statement "All chemicals in the lab (including foodstuffs and store-bought chemicals) should be treated as if they could be hazardous" is definitely true.

Chemicals may be characterized as any sort of basic substance that is significantly utilized in or manufactured during a reaction that involves remarkable alterations to atoms or molecules.

The methodology of treating chemicals demonstrates their physical as well as chemical properties, appearances, and reactiveness. In this way, one must become much more confidential with all the basic characteristics, potential hazards, and efficiency of any chemical.

This procedure also delivers proficiency to you in the future with respect to chemicals or their efficiency. It also decreases your potential fear of chemicals.  

Therefore, the statement "All chemicals in the lab (including foodstuffs and store-bought chemicals) should be treated as if they could be hazardous" is definitely true.

Answer:

b

Explanation:

There are two types of mixture, one is homogeneous mixture and other is heterogeneous mixture. Therefore, the correct option is option B that is the sand and gravel can be separated with a sieve.

When two or more compounds are combined but each ingredient retains its chemical identity, the result is referred to as a mixture. In other words, there is no chemical interaction between the parts of a combination. According to how consistent they are and how well the components' particle sizes match up, mixtures are categorized.

Sand and gravel in a mixture have the same properties as sand and gravel when they are not mixed. Since gravel is bigger than sand, the sand and gravel can be separated with a sieve.

Therefore, the correct option is option B.

The molecules among the given substances are: MgCl₂ (magnesium chloride). Option A is correct.

Molecules are formed when two or more atoms were chemically bonded together. Let's examine each of the given substances to determine if they are molecules:

MgCl₂ - This is a molecule. It consists of one magnesium atom (Mg) and two chlorine atoms (Cl) bonded together chemically, forming a compound known as magnesium chloride.

KH₂ - This is not a molecule. It consists of one potassium atom (K) and two hydrogen atoms (H) but lacks chemical bonding between them. Therefore, it is not a molecule.

Mg - This is not a molecule. It represents a single atom of magnesium (Mg) and does not involve bonding with other atoms.

Therefore, MgCl₂ (magnesium chloride) are the molecule.

Hence, Option A. is correct.

volume of cube = l^3

=2cm^3

=8cm^3

now,

mass=(9.7÷1000)kg

=0.0097kg

volume=8cm^3÷100=0.08

we know that,

density=mass/volume

= (0.0097/0.08)kg/m^3

= 0.12125kg/m^3

Explanation:

the formula to calculate volume of cube is l^3 so here we find the volume of cube using this formula and then we convert gram into kilogram then convert cm into m then by applying the formula of density we find it density

A 2 cm cube made of acrylic has a mass of 9.7 g. The density of the acrylic is 0.12125 kg m3

Density is the mass of per unit volume.

\(Volume of cube = l^3\\=2cm^3\\=8cm^3\)

mass 9.7 kg, converted into kilograms = 0.0097kg

\(Volume \;= \dfrac{8cm^3}{100} = 0.08\)

Calculating the density

\(Density = \dfrac{mass}{volume} \\\\\dfrac{0.0097}{0.08} = 0.12125\;kg\;m^3\)

Thus, the density of the acrylic is 0.12125 kg m^3.

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
